∗ When using solid state auto switches, ensure the application is set up so the signals for the fi rst 50 ms are invalid.
Connect according to the applicable PLC input specifi cations, as the connection method will vary depending on the PLC input specifi cations.
Because there is no
current leakage, the load
voltage will not increase
when turned OFF.
However, depending on
the number of auto
switches in the ON state,
the indicator lights may
sometimes grow dim or
not light up, due to the
dispersion and reduction
of the current fl owing to
the auto switches.
When two auto
switches are
connected in parallel,
malfunction may occur
because the load
voltage will increase
when in the OFF state.
Auto switches with load
voltage less than 20 V
cannot be used.
When two auto switches are
connected in series, a load
may malfunction because
the load voltage will decline
when in the ON state.
The indicator lights will light
up when both of the auto
switches are in the ON state.
(Reed)(Solid state)
Example: Load impedance is 3 kΩ.
Leakage current from auto switch is 1 mA.
Load voltage at OFF = Leakage current x 2 pcs. x
Load impedance
= 1 mA x 2 pcs. x 3 kΩ
= 6 V
Example: Power supply is 24 V DC
Internal voltage drop in auto switch is 4 V.
Load voltage at ON = Power supply voltage –
Residual voltage x 2 pcs.
= 24 V − 4 V x 2 pcs.
= 16 V
